Welcome to the NEW Crane Duet Concertina website.

The history of the Crane Duet, also known as the Triumph Duet or the Butterworth System, is not exactly shrouded in mystery, That said, much of the available information is scattered in different places. The aim of this site is to try and bring all of the pieces together, for the benefit of all owners and players, current and future, and, hopefully, to uncover information which has not been published before.

At the same time, we want the Gallery to grow to include examples of all of the varieties made over the years. If you're on this site, you know that all Cranes are " special" and should have a home in the gallery. The more information that we can put together on styles, serial numbers, etc, the better.

Because of their numbers, the Anglo & English systems dominate the world of concertinas. Within the Duet world, the Crane is overshadowed by the Maccann, yet it is the system most sought after by players either new or transitioning to Duet concertina.  Of course, those of us who play it can only nod our approval.

How many were made?  How many still exist?  What are their histories?  I hope this website will help to get us some way towards the answers.
